ADHESIVE-SUPPLYING MECHANISM.

Specification of Letters Patent.

Patented Aug. 13, 1907.

Application filed August 27 1901, Seria.l No. 73,410. Renewed June 15, 1907. Serial No. 379,129.

To all whom it may concern:

Be it known that I, OLUr` TYnRe, a citizen of the United States, residing at New York, county of Kings, and State of New York, have invented certain new and useful Improvements in Adhesive-Supplying Mechanisms, fully described and represented in the following lspecilication and the accompanying drawings, forming a part of the same.

This invention relates to certain improvements in adhesive supplying mechanism, and more particularly to mechanism which supplies the adhesive for retaining inclosing wrappers in position, such, for instance, as the wrappers of cigars.

The adhesive supplying devices now ordinarily employed in cigar machines may be divided generally into two classes. In the first of these classes, the end of the wrapper, before it is wound about the bunch, passes over the mouth of a fountain or well, the adhesive being smeared upon the wrapper as it moves across the mouth of the well. In the second class of constructions, which is more generally employed with machines which make cigars with one end closed, the adhesive is supplied to the wrapper as it is wound on the bunch by devices which deposit a quantity of adhesive at a single point, the adhesive being distributed over the surface to which it is to be applied by the pressure on the wrapper. In this second class of devices, the adhesive is liable to be supplied ina larger quantity than is necessary, and, furthermore, it is diiiicult to control the spreading action. It is, of course, obvious that in spreading the adhesive, it should be caused to move toward the extreme tip of the bunch so as to be always beneath the wrapper. In the practical operation of the devices referred to, however, the adhesive is liable to spread in both di- 4rections, thus smearing the outside of the Wrapper and causing the interior of the tip forming devices to become sticky and foul.

The present invention relates more particularly to the second class of devices, although mechanisms constructed in accordance with the invention may be used in connection with machines where adhesive is supplied to the wrapper before the wrapper is applied to the bunch, and has for its object to produce an adhesive supplyingmechanism of such a character that the adhesive may be supplied at the points where it is needed, thus avoiding the application of an undue quantity of adhesive at a single point and the smearing and fouling of the tip forming devices as a result thereof.

With this and other objects in view, the invention consists in certain constructions and in certain parts, improvements and combinations as will be hereinafter fully described and then specically pointed out in the claims hereunto appended.

4in connection with a cigar header.

In the accompanying drawings forming a part of this specification and in which like characters of reference indicate the same parts- Figure 1 is a plan view of an improved form of pasting mechanism constructed in accordance with the invention, said mechanism being shown in connection with the tip former or header of a cigar machine. Fig. 2 is an end elevation of the construction shown in Fig. 1, the position of the observer being indicated by the arrow 2 in said figure. Fig. 3 is a front elevation of the construction shown in Fig. l, the position of the observer being indicated by the arrow 3 in said figure. Fig. 4 is a section on the line Al/1 of Fig. 1. Fig. 5 is a detail sectional plan view on the line 5-5 of Fig. 4.

Referring to the drawings which illustrate one embodiment of the invention, 1 indicates a part of the frame of the machine and 2 indicates a supporting bracket which is secured thereto in any desired manner. In the present embodiment of the invention, the adhesive applying devices are shown as operating This header may be of any desired construction. As shown, it consists of two parts 3 and 4, the part 3 being shown as secured to the bracket in any suitable manner, as by screws 5, and the part 4 being movable on the part 3.

According to the present invention, the adhesive is supplied to the bunch at time intervals and at a plurality of points between the bunch and the wrapper or between the successive wraps or turns of the wrapper, said points being preferably distributed along the bunch and in a line running spirally around it, though they may be otherwise arranged.

, The devices by which the adhesive is supplied to the bunch may be widely varied in construction. As shown, the header is provided'with a plurality of orifices, four such orifices, marked 6, 7, 8 and 9 being shown, although the number may, of course, be varied, if desired. These orifices are arranged lengthwise of the header so as to deposit the adhesive in drops or small patches along the bunch to be wrapped. These orifices communicate with an adhesive containing chamber 10 which is shown as formed partly in the bracket 2 and partly in the lower part of the header block 3. The adhesive is supplied to the chamber 10 by means of a conduit which entends through the bracket 2 and is indicated in dotted lines in Fig. l, a nipple at the mouth of said conduit being marked 1I. The mouth of the conduit will be in communication through a suitable pipe with a reservoir and the adhesive will preferably be supplied from said reservoir to the chamber 1() under pressure.

Suitable means are employed for controlling the How of adhesive through the orifices 6, 7 8, 9, so as to cause the adhesive to be deposited at the desired times and at the desired points on the bunch. As shown, 110

these means consist of plungers 12, 13, 14 and 15. As each one of the plungers is drawn back, a quantity of adhesive will enter the orifice, the amount of adhesive depending upon the size of tho orifice, and as the plunger advances, the adhesive will be forced forward and deposited on the bunch. Suitable means are employed for operating the plungers. These means may be varied widely in construction, but they will prefer-abi y be of such a character that the plungers will be operated in succession. As shown, the plungers 12, 13 14 and 15 a-re engaged by levers 1G, 17, 18 andll, said levers being pivoted-on a rod 2() which is suitably supported in the bracket 2. It is obvious that when any one of the levers is operated its plunger will be moved. Any suitable means may be employed for operating the levers. As shown, a purality of cams 21, 22, 23 and 24 are employed, said cams being mounted on a shalt 25 suitably supported in the bracket 2. The

v shaft and cams are so located that as the shaft rotates,

the operative portions of the cams will strike the tails of the levers. The cams are preferably so positioned on the shaft, as has been before indicated, that the levers will be actuated and the plun gers thrown into operation in succession. While, however, the levers and the plungcrs are operated in succession, it may, under some circumstances, be desired to operate each lever and its cooperating plunger more than once before the next lever comes into operation. As shown, therefore, each of the cams 2l, 22, 23 and 2/1 is provided with two operating projections and the cams are staggered on the shaft, the construction being clearly indicated in Figs. 3 and l. While the. cams might be of such a construction as to operate the levers in both directions, when the cams illustrated vin the drawings are employed, suitable springs will be used to move the plungers in opposition to the cams. 1n the construction shown, plate springs, indicated at 26, 27, 28 and 29 are employed.

Any suitable means may be employed for rotating the shaft 25 to throw the cams into operation. As shown, this shaft is provided with a ratchet wheel 30, said wheel being engaged by a sliding pawl 31 mounted on a bracket 32 suitably secured to the frame of the machine. This pawl is guided in its movement by the pins 33, 34. Any suitable means may be employed for operating the pawl 31. As shown, a bell-crank lever 35, 36 is employed for this purpose, said bell-crank lever being pivoted at 37 to the bracket 2, and its arm 35 taking under a pin 38 secured to the pawl. The arm 36 may be operated in any suitable manner, as, for instance, by some moving part of the cigar machine, not shown. ln the construction shown, a spring 39 is used to return the pawl, said spring being secured to the pin 38 and to a pin 40 secured to the bracket 32.

The operation of the construction will be readily understood from the foregoing description. As the cigar bunch rotates in the header, the rotation of the shaft 25 and the cams carried thereon will cause the movement of the plungers which in turn will cause small patches or drops of adhesive to be applied at time intervals and at different points between the bunch and the wrapper, or between the wraps or turns of the wrapper'. It will be seen that when the plungers are operated in succession, the separated points at which the adhesive is applied will lie in a spiral line extending around the tip of the bunch. While, in the preferred form of the construction, the plungers will be successively operated, as has been indicated, it may, under some circumstances, be desirable to operate the plungers in sets, or under some circumstances, it might be desirable to operate them simultaneously. inasmuch as such changes in opera-tion merely involve changes in the form of the operating cams, any further description or illustration of them is regarded as unnecessary While the invention is more particulaly intended for use in connection with cigar machines, it will be readily understood that constructions which are embraced by it might be used in other relations where it is desired to secure a wrapper in position around an article. A While,

furthermore, the construction which has been described as embodying the invention is the preferred one, it is to be understood that it might be considerably varied. The invention is not, therefore to be limited .to the use described nor to the specific construction described, as

it may be embodied in other forms of construction.
